When it comes to naming all those exoplanets that astronomers keep finding, it’s up to the International Astronomical Union (IAU) to do the job. In an effort to reach out to the global community, they’re running a new contest. In honour of their 100 year anniversary, the IAU has organized the 100IAU NameExoWorlds event.Continue reading “Competition Will Let You Name an Exoplanet”
Whenever scientists announce an upcoming close encounter with an asteroid, certain corners of the internet light up like the synaptic rush that accompanies a meth binge, with panicky headlines shouted straight from the brain stem. But never mind that. We’re not that corner of the internet. We’re sober, yo!Continue reading “Don’t Worry About Asteroid 2006QV89. There’s Only a 1 in 7000 Chance It’ll Hit the Earth in September”
The ESA is developing its own spacecraft capable of re-entry into Earth’s atmosphere. The reusable spacecraft is called the Space RIDER (Reusable Integrated Demonstrator for Europe Return), and the ESA says that the Space Rider will be ready for launch by 2022. It’s being designed to launch on the Vega-C rocket from Europe’s spaceport in Kourou, French Guiana.Continue reading “Europe is Working On a Reusable Space Transport System: Space Rider”
The Beresheet lander came oh-so-close to touching down on the surface of the Moon, but something went wrong and it didn’t make it. Now, thanks to the Lunar Reconnaissance Orbiter, the exact point of impact can be seen.Continue reading “Here’s Where Beresheet Crashed into the Moon”
Think about this for a minute: We humans and our emissions are helping turn back the climatological clock by 2 or 3 million years, possibly more. Not since that time, called the Pliocene Epoch, has the CO2 ppm risen above 400.
Way back then, the CO2 helped keep the Earth’s temperature 2 to 3 degrees C warmer than it is now. And the Earth was a much different place back then.Continue reading “Today is the Highest Concentration of Atmospheric CO2 in Human History. 415 Parts Per Million. Last Time it Was This High, There Were Trees at the South Pole”
There are 20,000 objects orbiting Earth at this moment that are larger than 10 cm. Out of that number, only about 2,000 are operational satellites. The other 18,000 objects are pieces of junk of varying sizes. But it’s not just junk: it’s dangerous junk.
If that doesn’t sound like a problem, keep this in mind: Thanks to SpaceX and others, we’re living in the age of cheap access to space, and we’re seeing more and more satellites boosted into orbit. The problem won’t go away on its own.Continue reading “Before We Ruin the Universe, We Should Follow Some Space Sustainability Guidelines”
Have you heard of Interstellar Technologies? They’re the latest private company to launch their own rocket into space. They’re a Japanese company, and like other private space companies, their stated goal is to lower the cost to access space.Continue reading “Japan’s First Private Rocket Flies to Space”
Today’s breed of billionaire space entrepreneurs likes to keep us guessing, don’t they? Mr. Elon Musk is famous for announcing partial plans on Twitter, then leaving us to cajole the details out of him. Now, Jim Bezos, Amazon founder and Blue Origin visionary, is making us guess what an upcoming mysterious announcement might mean, all on the tails of another successful flight for New Shepard.Continue reading “Blue Origin’s New Shepard Flies Again, a Week Before Their Mysterious Announcement”
A new signal detected by LIGO/Virgo may be the so-called ‘holy grail’ of astrophysics: the merger of a neutron star and a black hole. They’ve discovered pairs of black holes merging, and pairs of neutron stars merging, but until now, not a neutron star-black hole pair.Continue reading “It Looks Like LIGO/Virgo Have Detected a Black Hole Eating a Neutron Star. For the First Time Ever”
In 2011, Microsoft co-founder Paul G. Allen and Scaled Composites founder Burt Rutan announced the creation of Stratolaunch Systems. With the goal of reducing the associated costs of space launches, the company set out to create the world’s largest air-launch-to-orbit system. After many years, these efforts bore fruit with the unveiling of the massive Scaled Composites Model 351 Stratolaunch air carrier in the Summer of 2017.
Similar in principle to Virgin Galactic’s SpaceShipTwo, this behemoth is designed to deploy rockets from high altitudes so they can send payloads to Low-Earth Orbit (LEO). After multiple tests involving engine preburns and taxiing on the runway, the aircraft made its inaugural flight last weekend (Saturday, April 13th) and flew for two and half hours before safely landing again in the Mojave Desert.Continue reading “The World’s Biggest Aircraft – the Rocket-Launching Stratolaunch – Completes its First Test Flight”
